I take it Keith is on some kind of calc hiatus; he hasn't posted in almost 2 months. Maybe someone should e-mail him to make sure he's not in a Turkish prison or something. If the project is being postposed I'd like to pick it up; but it'll be a while before I get Robot War out of the way to do anything.

Its not quite that simple, The Ti-89 uses a Motorola 68k chipset, and the Ti-83/83p/83pse all use the Zilog-80 (z80) chipset.

The motorola chipset is capable of doing a lot more, and its faster. If I'm not mistaken some of the first Apple computer's were actually based of this same serious of Motorolla chipsets.

This is a big project, and would be wonderful if anyone would be willing to revive, unfortunately I don't believe the codebase was ever shared so it would be starting over from scratch...this the third time.

Arent you knew to ASM shadowing? This would be a very hard project for somebody who is knew. Plus you cant port an 89 game to an 83, as AlienCC said, they use two different chipsets! I don't mean to put you down or anything, because you should create a game and push it to the limits, and make it the best you can! It's just that this would be an extremly difficult project for somebody just getting into ASM.

Oh..well It's just that I have never seen a game of this caliber on the 83. I don't think even if he could port it would be fast enough... Again...I am not putting you down Shadowing, just with all the features that the 89 version has....grayscale, parallax scrolling, high speed, external graphics-sprites-levels, huge levels, and a kit to create your own levels, graphics or sprites. Plus your just learning.

Well, to me its better to do something while I learn. I learned its better to try and learn in trial and error. That is what i believe it will make me a true programmer. Now can someone send me a link?

And Madskillz, you're not putting me down.

EDIT: Actually, you're just challenging me to push myself to my further limits.

Well, the original project was run by Time to Team [link has sound] and their [url="http://www.yaronet.com/t3/?id=2&d=archives/Games/Sonic%20(SMA)/source/"]latest source[/url] can only be found on their Sonic page. Porting would be a very tall order, even for an expert. The chipset difference doesn't just affect you code & syntax, it also affects your display capabilities; and thats were things could get messy. Then there's the code itself, which spans some 50 small source and header files--it would take weeks just to sort it out.

At the risk of being pessismistic: I seriously don't think a port can done without making it a team effort. And the death of this current Sonic project isn't too encouraging. But now that the source is out, there may be new hope.

Of course there have been a few games made for 89 that are also on the 83, Phoenix comes to mind....But Like I said, I didn't think you could port a C, C+ game to run a z80 chipset...they are two different languages.

-Good Shadowing! That is what you need to do! I know, how it is. If somebody told me a couldn't do something, that always motivated me to prove them wrong. Like I said, I wasn't trying to put you down...you obviously got that! If anything, I was subtly motivating you to make something cool/unique! You can always try and make something new and unique, even if you fail, as long as you put in an effort, people will appreciate it and maybe even try and help finish it! (that goes for everybody and every game)

It might be a longshot: but I'd try to get in touch with Time to Team, write down some emails, and see if they have any development notes from that program (the source commenting was a bit sparce). I'd also take a look at similar game like Mario to get a feel for how a Sonic/Mario-like game runs (collisions, scrolling, etc).
